Significance of Cellular Senescence in Aging and Cancer
1 Jan 2009
Abstract excerpt
Cellular senescence is a mechanism that induces an irreversible growth arrest in all somatic cells. Senescent cells are metabolically active but lack the capacity to replicate. Evolutionary theories suggest that cellular senescence is related to the organismal decline occurring in aging organisms.
